I know it works in forks, and even in my area. River dicks come back to flat tires! I dont have anything against sleds, its just the guys who use them wrongly. Even in a big river like the sky sleds suck when your in a driftboat. On the other hand being in a sled is nice too. Rippin' small rivers right next to you isn't cool. Take a stand....and a good buck knife.
